When you validate a batch, the program examines all the information entered in the batch to determine whether data entry errors exist. Before you update the status of a batch, we recommend you validate the batch to locate any data entry errors. When the program finishes its batch validation, a message appears to tell you the results of the validation. For each data entry error found, an exception is created and appears on the batch data entry screen. To submit or approve the batch without difficulty, correct any exceptions found.
